As training camps have opened throughout the league, NFL Network analyst Charley Casserly discussed the Jets’ quarterback situation, the Giants’ new offense and whether or not Johnny Football will start from the get-go with The Post’s John DeMarzo.

Q: Geno Smith appears to be the guy for the Jets, but is there a chance Michael Vick can unseat him?A: I don’t see it happening in training camp. It’s Geno’s job to lose and he can’t lose it in camp. Vick is coming in to be the backup. [He may start] if Geno disintegrates, but that’s hard to happen…I’m not sure you have a good answer if you have to go to Vick. You ride this thing with Geno and see how he develops.

Q: What do you make of the Giants, with all of their new players and a new offense to learn under offensive coordinator Ben McAdoo?A: They’re a better team on paper in many ways, but you have too many moving parts in too many new areas.

At wide receiver, you’re bringing in a first-round pick in [Odell] Beckham Jr. who has talent, so you need to get him in there.

On the offensive line, left tackle didn’t change and that was their biggest problem. Running back, there’s a whole new crew there. [Rashad] Jennings is the bell cow, but will [David] Wilson stay healthy?…It’s a whole new system. That’s a lot of moving parts. It’s going to take time for the players to get it and the coaches to understand it.

Q: On the heels of his tumultuous offseason, how would you handle Johnny Manziel, and do you think he will be the Week 1 starter for the Browns?A: [I would say to him], no endorsements Year One. No radio or TV shows. What did Peyton [Manning] do when he came into the league? [Andrew] Luck? No distractions. We want [him] totally focused on football…It’s unfair to expect a lot out of him this year. [With Josh] Gordon facing a drug suspension, he doesn’t really have…the Andre Johnson-[type] player to catch 100 balls…It’s [Brian] Hoyer’s job for the time being. [He’s] more experienced — so many unknowns about Manziel.

Q: Which team intrigues you the most this season?A: The Bears. It’s their second year with [head coach Marc] Trestman, second year with some of those players together and maturing, and I think it’s a dynamic group…This is a playoff offense. The question is [Jay] Cutler. Will he be consistent enough and stay healthy?…[They’re] better on defense and I think the offense takes another step up.

Q: What team do you think could take a step back this year?A: The Panthers. [Coach] Ron Rivera did a hell of a job and so did [general manager] Dave Gettleman, but they’re still recovering from the [salary] cap.

They did a good job signing one-year type free agents for not a lot of money. They tried to do that with receiver, like [Jerricho] Cotchery.

They’re veteran guys, but they’re not hard to defend…New Orleans made the playoffs last year, Atlanta will be better, and Tampa Bay is on the rise. It will be a tougher division.
